Abstract

1385705 Measuring fluid pressure electrically JOSEPH LUCAS (INDUSTRIES) Ltd 17 March 1972 [26 March 1971] 8218/71 Heading GIN The description is identical with that of Specification 1386082 but the claims are directed to the bellows assembly 20 (Fig. 3) and the electromagnetic force applying device 24 which restores the bellows to substantially its normal position when expanded or contracted axially by the best pressure.
